P0D6E code meaning
A/C Compressor Motor Voltage A High
What P0D6E means
P0D6E means the high voltage supplied to the electric A/C compressor motor is above what the compressor is built to accept, as opposed to a sensor circuit reading too high (P0D6A). No manufacturer documents P0D6E publicly. GM handles the situation its own way: the 2011–2015 Volt and 2016 ELR compressor sets P0D6A at 450 V or more and a separate maker code, P1ECA, for a single peak of 480 V; Mitsubishi's Outlander PHEV treats over 415 V for 2 s as P0D6A. Real overvoltage is rare because the traction battery clamps the bus; possible triggers are spikes during charging or regeneration, a faulty charger or converter, or a misreading inverter. The compressor usually shuts down to protect its power stage. CARB covers such inputs under hybrid thermal-management monitoring.
P0D6E at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0D6E
- Air conditioning switches off
- Possibly further high-voltage codes
- Warning message depending on the vehicle
Common causes of P0D6E
- PossibleVoltage measurement in the compressor inverter reads too high
- Less likelyVoltage spikes on the high-voltage bus during charging or regeneration
- Less likelyCharger or DC/DC converter regulating the bus voltage incorrectly
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0D6E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6E | The exact fault in that area. |
What to do next
- Note P0D6E and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0D6E
What does P0D6E mean?
P0D6E means "A/C Compressor Motor Voltage A High". P0D6E means the high voltage supplied to the electric A/C compressor motor is above what the compressor is built to accept, as opposed to a sensor circuit reading too high (P0D6A). It is a generic code, so it means the same on every make.
Is it safe to drive with P0D6E?
P0D6E does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0D6E fail an emissions test?
P0D6E is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0D6E to fix?
Difficulty: workshop only. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0D6E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
